Lansdowne Hospital Regeneration Reaches Completion — Full handover Delivers £30m Social Housing Vision
This week marks a significant milestone for Dennis Hellyar Architects and the wider project team — the full handover of the Lansdowne Hospital regeneration in Cardiff, one of the most ambitious social housing schemes we have been involved with to date.
The development, delivered by Lovell Partnerships for Hafod Housing Association, in partnership with Cardiff Council and the Welsh Government, has transformed a prominent brownfield site on Sanitorium Road into 106 energy-efficient new homes. The scheme comprises 44 houses and 62 apartments, alongside generous green spaces, a communal sensory garden, and the refurbished former doctors' house which will serve as a community space for new residents and the wider neighbourhood.
Construction began in August 2023, with the first 66 homes handed over to residents earlier in the development programme. This week sees the completion and full handover of the entire development — a moment the whole team has worked towards since the project began back in 2018.
Designing with the Placemaking Wales Charter at Heart
For us as a leading Cardiff Architectural firm, this project has always been about more than buildings. From the outset, the design approach was guided by the principles of the Placemaking Wales Charter; the framework developed by the Welsh Government and the Design Commission for Wales to ensure new developments genuinely serve the communities they are built for.
Those principles shaped every decision across the masterplan:
involving the local community in proposals
choosing a highly sustainable urban location with excellent access to public transport and active travel routes
creating well-defined streets and public spaces that feel safe and welcoming, and
respecting and enhancing the distinctive character of the area.
The retention and refurbishment of the locally listed former doctors' house is a perfect example of this ethos in practice - honouring the heritage of the site while giving it a new purpose for future generations.
Sustainability Built In
All 106 homes achieve an EPC A rating, with air source heat pumps providing low-carbon heating and a fabric-first approach ensuring homes are highly insulated and efficient by design. The landscape strategy incorporates extensive green infrastructure, rain gardens with gravel-filled depressions to manage surface water, and enhanced biodiversity throughout the site. Many existing trees have been retained, weaving established greenery into the new neighbourhood from day one.
The scheme is a strong example of what is possible when a leading Cardiff architectural firm approaches regeneration with genuine long-term thinking; designing for climate resilience, community wellbeing, and sustainable living in equal measure.
A Neighbourhood for All Stages of Life
As Hafod's spokesperson noted recently, the scheme is designed to offer accommodation that supports people through different stages of their lives. That ambition is reflected in the mix of house sizes, specialist apartments designed for residents with disabilities or care needs, and shared external balcony corridors that encourage neighbourliness rather than isolation. This is placemaking in the truest sense of the word.
